Combined case and stand for thermometers



June 25, 1935. B, SCHUPP 2,005,909 1 COMBINED CASE AND STAND FOR THERMOMETERS Filed June 27, 1954 J/fz'ed SCAH/Of) [NVEWOR ATTORNEY Patented June 25, 1935 UNITED STATES PATENT OFFICE COIWBINED CASE AND STAND FOR THERMOIVETERS 3 Claims.

This invention relates to the protection of thermometers when not open or in an operative position; to test the temperature of a refrigerator, an oven or any other appliance in which the temperature is of vital importance, an inspector or mechanic, intending to inspect or correct any fault must provide himself with a thermometer.

The object of this invention is to provide a safe case to protect the thermometer against breakage when carried in the pocket or tool-case, and when testing to provide a stand when the case is opened; a further object is to provide a neat desk thermometer when open and which when not in use can be quickly folded down to a closed and locked position.

In the accompanying drawing which forms a part of this specification these objects are accomplished. Fig. 1 is a perspective view of the case closed; Fig. 2 is a longitudinal centre section showing the cover open; Fig. 3 is a front elevation of Fig. 2 and Fig. 4 is an enlarged section on line :c-w of Fig. 2, partly broken away, to show the means by which the cover is held in an opened position or locked when closed.

Similar reference characters refer to like parts in the several views.

The device consists of a flat cover, I, having longitudinal flanges, I, I", provided with slots, 2, 2 extending partly downward. The thermom eter and scale, 3, is fastened on the inner side of the cover. The base or stand has longitudinal flanges, 4, 4", the space between them being slightly wider apart so that the flanges of the cover will neatly fold inside of the base, 4, as shown; at diametrically opposite points these flanges are pierced, 5, for the reception of a wire, 6, which acts as a pivot upon which the cover, by means of the slots 2, 2' articulates when extended. After passing through the slots the wire is bent down at right angles to extend across the inner bottom of the base to the opposite flange where the wire is similarly bent, as shown in Fig. 4. A section of the bottom is broached out upwardly to form a spring, 1, which engages the wire, 6, centrally, and acts as a frictional means to hold the cover open when extended. A projection, 8, near the top of the cover indicates the top or free end of the cover.

I prefer to make the case of aluminum, that being the most suitable metal.

The operation is as follows; to open the case, the cover is slid forward or outward parallel with the base until it comes to a stop on the wire when it can be raised and held in an upright position by the wire and spring. To close reverse the operation, and when in closed position the wire at the flanges holds the cover down so it cannot be raised; the only way to open the case is to slide the cover outward; the dash line on Fig. 2, shows the arc of travel of the cover.

The thermometer and scale forms no part of this invention as it may be of the ordinary graduation, as for desk use, or for low temperature, as for refrigerators, or for high temperatures, as for ovens, etc.

What I claim is,

1. A foldable thermometer case comprising a flat base member having a pair of spaced parallel side flanges perpendicular thereto, an inwardly extending tongue on the base member between said flanges, a cover member having a pair of spaced parallel side flanges provided with transversely aligned longitudinal slots, a wire disposed transversely across the bottom of said base member beneath said tongue and having upturned ends provided with laterally bent terminals passed through the cover flange slots and anchored in the base member flanges whereby to provide slidable and pivotal connection between member of channelled cross-section disposed between the channel flanges of the base member in inverted relation thereto, means slidably and pivotally connecting the channel flanges of said base and cover, and said connecting means having a portion disposed beneath and reinforcing said tongue.

3. A foldable thermometer case comprising a pair of open ended channel members slidably nestable in opposed relation, a slot and pin connection between the flanges of said members, and one of said members having an inturned tongue engageable by an end of the other member whereby to hold it in raised position when swung on said slot and pin connection as a pivot.
